Linus Torvalds1da177e2005-04-16 15:20:36 -070012 Unless you really know what you are doing, you should say Y here.
13 The reason is that some programs need kernel networking support even
14 when running on a stand-alone machine that isn't connected to any
Sam Ravnborgd5950b42005-07-11 21:03:49 -070015 other computer.

Sam Ravnborgd5950b42005-07-11 21:03:49 -070017 If you are upgrading from an older kernel, you
Linus Torvalds1da177e2005-04-16 15:20:36 -070018 should consider updating your networking tools too because changes
19 in the kernel and the tools often go hand in hand. The tools are
20 contained in the package net-tools, the location and version number
21 of which are given in <file:Documentation/Changes>.

23 For a general introduction to Linux networking, it is highly
24 recommended to read the NET-HOWTO, available from

40 This option makes it possible to send different netlink messages
41 to tasks depending on whether the task is a compat task or not. To
42 achieve this, you need to set skb_shinfo(skb)->frag_list to the
43 compat skb before sending the skb, the netlink code will sort out
44 which message to actually pass to the task.
45
46 Newly written code should NEVER need this option but do

Pablo Neira Ayusoef91fd52006-11-29 02:35:43 +0100143 bool "Network packet filtering framework (Netfilter)"
Masahiro Yamadaa7f7f622020-06-14 01:50:22 +0900144 help
Linus Torvalds1da177e2005-04-16 15:20:36 -0700145 Netfilter is a framework for filtering and mangling network packets
146 that pass through your Linux box.
147
148 The most common use of packet filtering is to run your Linux box as
149 a firewall protecting a local network from the Internet. The type of
150 firewall provided by this kernel support is called a "packet
151 filter", which means that it can reject individual network packets
152 based on type, source, destination etc. The other kind of firewall,
153 a "proxy-based" one, is more secure but more intrusive and more
154 bothersome to set up; it inspects the network traffic much more
155 closely, modifies it and has knowledge about the higher level
156 protocols, which a packet filter lacks. Moreover, proxy-based
157 firewalls often require changes to the programs running on the local
158 clients. Proxy-based firewalls don't need support by the kernel, but
159 they are often combined with a packet filter, which only works if
160 you say Y here.
161
162 You should also say Y here if you intend to use your Linux box as
163 the gateway to the Internet for a local network of machines without
164 globally valid IP addresses. This is called "masquerading": if one
165 of the computers on your local network wants to send something to
166 the outside, your box can "masquerade" as that computer, i.e. it
167 forwards the traffic to the intended outside destination, but
168 modifies the packets to make it look like they came from the
169 firewall box itself. It works both ways: if the outside host
170 replies, the Linux box will silently forward the traffic to the
171 correct local computer. This way, the computers on your local net
172 are completely invisible to the outside world, even though they can
173 reach the outside and can receive replies. It is even possible to
174 run globally visible servers from within a masqueraded local network
175 using a mechanism called portforwarding. Masquerading is also often
176 called NAT (Network Address Translation).
177
178 Another use of Netfilter is in transparent proxying: if a machine on
179 the local network tries to connect to an outside host, your Linux
180 box can transparently forward the traffic to a local server,
181 typically a caching proxy server.
182
183 Yet another use of Netfilter is building a bridging firewall. Using
184 a bridge with Network packet filtering enabled makes iptables "see"
185 the bridged traffic. For filtering on the lower network and Ethernet
186 protocols over the bridge, use ebtables (under bridge netfilter
187 configuration).
188
189 Various modules exist for netfilter which replace the previous
190 masquerading (ipmasqadm), packet filtering (ipchains), transparent
191 proxying, and portforwarding mechanisms. Please see
192 <file:Documentation/Changes> under "iptables" for the location of
193 these packages.

352 backlog reaches netdev_max_backlog. If a few out of many active flows
353 generate the vast majority of load, drop their traffic earlier to
354 maintain capacity for the other flows. This feature provides servers
355 with many clients some protection against DoS by a single (spoofed)
356 flow that greatly exceeds average workload.

483 The failover module provides a generic interface for paravirtual

486 handle netdev register/unregister/link change/name change events

488 failover netdev. This enables paravirtual drivers to use a
